2008年2月24日，富山县东海岸发生了被当地居民称为“约里马瓦纳美”的长波大浪。特别是大浪给牛原镇的石崎区造成了巨大的人员和财产损失。本研究的目的是，首先，在实地调查中检查由浪涌引起的海岸损害。在此基础上，利用GFS-WRF-SWAN耦合模型进行波浪后推，并利用二维数值波浪水槽“CADMAS-SURF”对Ashisaki地区护岸波浪过顶进行数值模拟，探讨了缓坡型护岸高波浪变形、波浪过顶和住宅小区淹没流的特征。
High wave with long wave period, which is known by local residents as “Yorimawari-Nami”, hit the east coast of Toyama Prefecture on February 24, 2008. The high wave, in particular, caused huge human and property damages in Ashisaki district of Nyuzen town. The purpose of this study is, at first, to examine coastal damages induced by the swelllike wave throughout filed surveys. The characteristics of high wave deformation, wave overtopping of a gentle-slop type revetment and inundation flow in the residential area are, furthermore, discussed by performing wave hindcasting with a GFS-WRF-SWAN coupled model and numerical simulation on wave overtopping of the revetment in Ashisaki district using a two-dimensional numerical wave flume “CADMAS-SURF”.
